Animal dissection in education is generally accepted as a warranted instructional tool. The investigation of body systems, structure, and function is the basis for studying the internal anatomy of several species. Some believe that dissections enable students to refine and enhance analytical and organizational skills as well as gain practical exploratory abilities (Bowd, 1993). Exercises in dissection may also teach manual dexterity and spatial analysis which is important for students who go on to veterinary and medical schools and must practice surgical skills (Valli, 2001). Several species of animals are used in dissections including Marine Invertebrates, Terrestrial Insects, Crustaceans, Frogs, Rats, Salamanders, Dogfish Sharks, and Fetal Pigs. Although the total number of animals used in dissection each year is hard to come by, it is estimated that tens of millions of animals are dissected every year in North America. The continued use of animal dissection in schools is a controversial topic. Here are a few pages to introduce some of the welfare issues associated with dissection and the alternatives that are beginning to prove themselves as comparable learning tools.
